Numerous studies in urban resilience have been published in the past decade. However, only a few publications have tracked the evolution trends of urban resilience research, the findings of which can serve as a useful guide for scholars to foresee worth-effort research areas and make the best use of precious time and resources. In order to fill the research gap, this study performed a scientometric analysis on the evolution trends of urban resilience research using a versatile software package-CiteSpace. The scientomentric analysis focuses on distribution of lead authors and their institutions, high frequency categories and keywords, high influential journals, author contribution, and evolutionary trends based on co-author analysis, co-word analysis, co-citation analysis and cluster analysis of documents. This study discoveries that first, the U.S., England, Australia, Canada, China and Sweden are the countries that make the most significant contributions in the advancement of urban resilience research; second, the existing urban resilience research focuses primarily on environmental studies, geography and planning development; third, hot topics of the urban resilience research keep shifting from 1993 to 2016; fourth, the knowledge body of urban resilience research consists of five clusters: resilience exploratory analysis, disaster resilience, urban resilience, urban resilience practice, and social-ecological systems; last, the emerging trends in urban resilience research include defining urban resilience, adaptation model, case studies, analytical methods and urban social-ecological systems, resulting in cutting-edge research areas in urban resilience.

Purpose: This paper aimed to introduce a systematic body of knowledge via a scientometric review, guiding the sustainable transition from conventional construction to prefabricated construction. The construction industry currently faces a challenge to balance sustainable development and the construction of new buildings. In this context, one of the most recent debates is prefabricated construction. As an emerging construction approach, although existing knowledge makes contributions to the implementation of prefabricated construction, there is a lack of a comprehensive and in-depth overview of the critical knowledge themes and gaps.Design/methodology/approach: This study uses the scientometric analysis to review the state-of-the-art knowledge of prefabricated construction. It retrieved data from the Web of Science core collection database. CiteSpace software was used to conduct the analysis and visualization; three analysis methods identify the knowledge hotspots, knowledge domains and knowledge topics. Finally, according to integrating the hidden connections among results, a body of knowledge for prefabricated construction application can be inferred.Findings: The results show that 120 knowledge hotspots, five critical knowledge domains and five prominent knowledge topics are vital for promoting implementation of prefabricated construction. Based on the afore analysis, a body of knowledge for prefabricated construction that can systematically cover a broad knowledge of prefabricated construction-related research and activities are integrated and proposed in this paper.Originality/value: Body of knowledge systematically covers a broad knowledge of prefabricated construction applications and is vital to guide researchers and practitioners to conduct related research and activities, thereby promoting the sustainable transition to prefabricated construction implementation.

Sustainable construction requires effective innovation in construction projects. Innovations involved multiple professionals and participants, inter-organization collaborative among stakeholders is considered as a feature and basic demand for innovation management. Exploring complicated interaction relations of stakeholders in inter-organization collaborative innovation, which is an important guarantee to realize innovation in sustainable construction. The network was viewed as a complex system that can replace stable organizational structure and procedures. It is necessary to shed light on the internal mechanism of innovation from the network perspective to promote the performance of innovation. This article investigates the project network of an industrial construction project in China by adopting the social network method and in-depth quantitative data analysis. Based on the network data and qualitative interview, the structure of the project network in the process of innovation for sustainable construction is analyzed, the key actor in the innovation management is revealed, and the influence factors of the inter-organization collaborative is pointed out. Research results will help promote the inter-organization collaborative innovation and improve the efficiency of sustainable construction.

Application of emerging digital technology (DT) is an attractive subject of research and is indispensable to the current goal of intelligent construction in many countries. Relevant studies have either focused on the status of a specific DT or proposed preliminary/qualitative comparisons among DTs. This paper provides a systematic understanding of research on applying DTs to the architecture, engineering, construction, and operation (AECO) industry using a mixed-review method. Ten emerging DTs are determined, and publications related to them in 2011–2020 are collected from the Scopus database. The overall status and comparisons of research on 10 emerging DTs by region, journal, and popularity are then presented. The content of research on them is examined through in-depth literature analysis (including research scenario, project stage, and literature evolution in a discipline) and theme classification. Future research directions including technology knowledge, development, application and management, and some practical implications for the country, industry, project, and enterprise, are finally proposed. This research will be informative for academics with regard to the emerging DT’s opportunities in this discipline and provide support for work on the digitization of the AECO industry. Some practical implications are proposed from the perspectives of the country, industry, project, and enterprise. For the government, the holistic planning and scientific coordination of emerging DTs need to be highlighted, such as vigorously promoting Building Information Modelling (BIM) and artificial intelligence (AI) and utilizing them to further support the progress of blockchain and digital twin. Establishing demonstration projects to play their radiating roles and accelerate the inter-regional promotion of emerging DTs is also effective. For the industry, it is suggested to build technology alliances to jointly develop integrated platforms covering multiple emerging DTs through in-depth synergy; industry associations are advised to strengthen knowledge diffusion and accumulation for emerging DTs through sharing and training. For projects, applying emerging DTs to the entire life of projects and making them be deeply integrated with off-site, lean, and green construction are advisable. For enterprises, improving the workflow and management model adapted to the application of emerging DTs is necessary. Through adjusting organizational structure and transforming corporate culture, the competitiveness of enterprises could be continuously improved.
